From the statement select the related given statement. in a triangle a segment joining the midpoints of two sides is one-half the length of the third side. plane r is parallel to plane s; plane t cuts planes r and s. △abc with ∠1 = ∠2. point b is between points a and c line l; point p not on l. △abc with midpoints m and n.

△ ABC with midpoints M and N.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

source:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
